一道阅读36套上的题求指点~

WWOWUID: 3649627

这是Exercise 11第二篇文章的一段节选：

The deep sea typically has a sparse fauna dominated by tiny worms and crustaceans, with an even sparser distribution of larger animals. However, near hydrothermal vents, areas of the ocean where warm water emerges from subterranean sources, live remarkable densities of huge clams, blind crabs, and fish.

这是一道多选题目：
5. The passage provides information for answering which of the following questions EXCEPT?
□A What causes warm-water vents to form?
□B What role does hydrogen sulfide play in chemosynthesis?
□C Do bacteria live in the vent water of smokers?

答案是AB。关于A选项，文中提到了warm water是从subterranean sources来的，为何还要选A呢？求大神指点~~谢谢

但在这段中已经能找到A选项问题的答案了，就说明不能选A选项了吧？因为题中问的是不能在原文中找到答案的问题~有点绕，不知道这么理解对不对

A说的是form不是from

之前以为subterranean sources就是vent的形成原因，看来这个只是来源，和form还是有区别的。多谢版主！:)
